JOHN P. MALONEY, OF WOONS OCKE'I, RHODE ISLAND.

SHUTTLE-CHECK FOR Looms.

SPECIFICATION forming part of Letters Patent No. 661,665, dated November13, 1900.

Application filed May 18, 1900. Serial No- 17,l64:. (No model.) 7

To all whom it may concern:

Be it known that I, JOHN P. MALONEY, a citizen of the United States ofAmerica, residing at No. 21 Hope street, in the city of Woonsocket,county of Providence, and State of Rhode Island, have invented certainnew and useful Improvements in Shuttle-Checks for Looms, of which thefollowing is a specification.

This invention relates to an improvement in shuttle-checks for looms;and the object of my invention is to check the force of the shuttlegradually as it'strikes against the picker in the box, therebypreventing the cop or bobbin from breaking.

It consists in the arrangement of parts adapted to be applied tothelower portion of the picker-stick, as hereinafter fully described andclaimed.

Figure 1 of the accompanying drawings is a partial front elevation ofone end of a loom, showing the position of my device as secured to thestep of the picker-stick. Fig. 2 is a perspective view of theattachment. Fig. 3 is an enlarged side elevation of my device andshowing that portion of the picker-stick to which it is applied. Fig. 4is a top planview of the same. Fig. 5 is a rearend View of my device assecured to the step ofthe picker-stick.

Like letters of reference indicate like parts. A designates thepicker-sticlgwhich swings upon the step b, c the picker secured to thepicker-stick, and d the lay or shuttle box. All these parts are of theusual construction. E indicates my improved checking device, whichoperates in conjunction with the pickerstiok. This checking devicecomprises an angle-rod F,which is bent as shown and having one endmounted and secured upon an outward extension g, integral with the stepb, by a bolt h, (see Fig. 4,) said angle-rod having a longitudinal rearportion f, squareshaped in cross-section, as shown in Fig. 5.

G indicates a socket-piece having a circular recess t' longitudinallydisposed and also provided with an opening j, arranged longitudinallythrough from each end thereof, said socket-piece adapted to be mountedupon the rear portion f of said angle-rod through said opening j, with avertical screw-tapped aperture 7 s in said socket-piece to receive asetscrew Z.

H indicates a pin which passes through a circular opening m in thesocket-piece and formed centrally with the circular recess 1' of thesame, said pin having an enlarged semispherical head n integraltherewith at one end thereof.

I indicates a coil-spring placed in the circular recess t' of thesocket-piece and surrounding the pin H and is designed to impingeagainst the head it of the same.

J indicates a collar mounted upon the projecting end portion of the pinH and provided with a screw-threaded aperture 0 to receive a set-screwo, adapted to hold the said pin in position to which it is moved.

In practice the socket-piece G assumes a longitudinal position at thelower rear portion of the picker-stick, with the axis of the pin H inalinement with the vertical center of the picker-stick.

In the operation of box-looms it frequently happens that when theshuttle comes in contact with the swell s in the box the force of theshuttle causes the cop or bobbin to break and making waste of thefilling or bobbin for use again. I obviate this difficulty, as with mydevice the pressure of the swell in the boX is made comparatively loose,so that when the shuttle strikes against the same the force is lesseneduntil the shuttle reaches the picker, when the picker-stick will swingrearwardly and gradually stop the movement in the stroke of the shuttle.With my tension device as applied to the lower portion of thepicker-stick I have not only the advantage of obtaining a readyadjustment of tension upon the picker-stick, but also an increase ofleverage in the throw of the picker, and thereby giving a softer checkto the shuttle.

Having described my invention, what I claim is- In combination with thepicker-stick of a box-loom, of the angle-rod F having one end mountedand secured at the side of the step of the picker-stick and bent asshown, the socket-piece G adjustably mounted on said angle-rod andprovided with a circular recess longitudinally disposed, the pin Hhaving an enlarged head n integral therewith at one end thereof, saidpin adapted to pass through the said socket-piece and longitudinallycentral with the circular recess thereof, the spring I in the recess ofsaid socket-piece and suradapted to hold said pin in position to which10 it is moved, substantially as described.

Signed by me at Providence, Rhode Island, this 15th day of May, 1900.

JOHN P. MALONEY.
